Action to present embodiment gathers explanation.

First, the current that are supplied to the suds of Cold water supply mouth 74c by suction inlet 34a are rotated in rotation stream 74d.And then the current that utilize the suds in rotation stream 74d to be rotated carry out initial stage mixing to these suds and the compressed air that is supplied to air inlet 74e, import to import road L via internal space S 1.Be directed to the rotation based on the first impeller 82 and form of being carried upward by above-mentioned slot part 83 spreads with the suds that are easily trapped in downside of the gas-liquid (being suds and compressed air) that imports road L, via all groove G1, be imported into the first mixing chamber C1.Now, the contrary direction rotation of flow direction that the first impeller 82 is rotated along suds with above-mentioned rotation stream 74d etc., thus, larger current difference is paid gas-liquid interface as cut-out power, has realized the promotion to gas-liquid mixed.

Next, be imported into the circumferential Hybrid that flows and cut off by a plurality of cowling panels 76 that the gas-liquid of the first mixing chamber C1 produces to be accompanied by the rotation of the first impeller 82, and be directed to internal space S 2.The deviation that the gas-liquid for flow direction that the impact of the cowling panel 76 when now, medial flange 75c does not exist concavo-convex tabular surface 77 to relax because of gas-liquid mixed by forming cowling panel etc. produces distributes.

The gas-liquid that imports to internal space S 3 from internal space S 2 is directed to the second mixing chamber C2, the rotation based on the second impeller 84 and mixing in the same way.And then this mixed gas-liquid is imported into the 3rd mixing chamber C3 via all groove G2, further mixes.The gas-liquid distribution bias for flow direction that the impact of the cowling panel 79 when now, medial flange 78c does not exist concavo-convex tabular surface 80 to relax because of gas-liquid mixed by forming cowling panel etc. produces.

The gas-liquid of mixing is in the above described manner discharged from outlet 34c as the foam W consisting of micro-bubble group.As described above, this foam W is supplied in bathtub 10 via foam pipeline 41a, 41b etc.

As described in detail above, according to the first embodiment, can access following effect.

(1) in the present embodiment, being directed to circumferential the flowing that gas-liquid in the first～three mixing chamber C1～C3 produces to be accompanied by the rotation of the first and second impeller 82,84 is mixed by the mode that the outstanding a plurality of cowling panels that arrange 76,79 cut off along circumferentially spaced compartment of terrain.In other words, the related gas-liquid mixed of bubble formation by being formed on the first mixing chamber C1 between the second housing 75 and the first impeller 82, be formed on the second mixing chamber C2 between the second housing 75 and the second impeller 84, the 3rd mixing chamber C3 being formed between the 3rd shell 78 and the second impeller 84 and intensively carry out respectively.Therefore, can more save and carry out spatially the related gas-liquid mixed of bubble formation.

(2) in the present embodiment, by the tabular surface of medial flange 75c, 78c 77,80 is formed to flat condition, and do not configure cowling panel etc., the deviation that the gas-liquid for flow direction that the impact of the cowling panel 76,79 while having relaxed thus because of gas-liquid mixed produces distributes, can carry out the gas-liquid mixed in the downstream of this cowling panel 76,79 more efficiently.

(3) in the present embodiment, by before importing gas-liquid towards the first mixing chamber C1, the current that utilize the suds in rotation stream 74d to be rotated mix with the compressed air initial stage of carrying out of supplying with from air inlet 74e these suds, can carry out more efficiently gas-liquid mixed as a whole thus.

(4) in the present embodiment, the direction of rotation of the first impeller 82 is set as the contrary direction of flow direction being rotated with the suds that rotate in stream 74d.Therefore,, in the first mixing chamber C1, because the larger current difference having improved after the flowing velocity that suds are rotated is paid gas-liquid interface as cut-out power, therefore can further promote gas-liquid mixed, and then can more save and carry out spatially gas-liquid mixed.

(5) in the present embodiment, import that gas-liquid in the L of road is accompanied by the rotation of the first impeller 82 with suds and the mode of being carried by a plurality of slot parts 83 along the configuration of circumferentially spaced compartment of terrain spreads.In other words, Gas-Liquid Dispersion possesses lid 74a(lid side perisporium 74g being formed at) the first housing 74 and first impeller 82(the first 82a of plectane portion, upstream side perisporium 82b) between importing road L in carry out.Therefore, can relax the deviation that the gas-liquid for the flow direction of gas-liquid distributes, and energy now only can be delivered to the gas-liquid being present in the region that need to be rotated, can make thus the gas-liquid mixed in the middle of the downstream of above-mentioned zone that is the first mixing chamber C1 etc. more efficient.

(6) in the present embodiment, can utilize the foam W that the micro-bubble group that generated by MBF generating apparatus 34 forms to carry out the outstanding foam bath of texture.

(7) in the present embodiment, by making the first impeller 82 have the function of gas-liquid mixed and the function of Gas-Liquid Dispersion concurrently, compare with the situation that for example makes two impellers there is respectively above-mentioned functions, can reduce number of components.

(8) in the present embodiment, the Gas-Liquid Dispersion by utilizing multistage mixing chamber C1～C3 repeatedly to carry out gas-liquid mixed and occur at tabular surface 77,80, can generate trickleer foam W thus.

(9) in the present embodiment, by the functions such as gas-liquid mixed and Gas-Liquid Dispersion are intensively built in to MBF generating apparatus 34, thus can be efficiently and more save disposable continuous generation micro-bubble group spatially.

(10) in the present embodiment, by utilizing the MBF generating apparatus 34 being connected with the outlet of circulating pump 47 to generate or regenerating, be accompanied by the foam W that circulation disappears or worsens, can proceed thus the outstanding foam bath of texture.That is, can utilize the heating of foam W of circulation and generation or regeneration to continue to utilize the warm foam W being formed by micro-bubble group to take a shower.Therefore and because the water content of the foam W consisting of micro-bubble group is more, thermal capacity is also larger, also can suppress in accumulating, the temperature of the foam W in taking a shower reduces.

(11) in the present embodiment, even if the foam W circulating dries out and forms loose state, can again generate high-quality foam W by increase a small amount of moisture or warm water in MBF generating apparatus 34, therefore, for example compare with the situation of foam generated W from the beginning, can generate efficiently or again claim foam W.; the in the situation that of foam generated W from the beginning, the water content that foam W integral body need to be occupied is for example made as 0%～25%, on the other hand; by circulate again foam generated W in the situation that, the water content of only foam W integral body being occupied is for example made as 15%～25%.

And, because the foam W of circulation has heat to a certain extent, therefore, for example, compare with the situation that regenerates foam W, can heat efficiently and generate or foam generated W again.That is, the in the situation that of foam generated W from the beginning, foam W need to be heated to 43 ° of C from for example 23 ° of C, in the situation that utilization circulates again foam generated W, as long as foam W is heated to 43 ° of C from for example 38 ° of C.As mentioned above, can reduce the energy consumption in foam bath as a whole.

(12) cowling panel, along the circumferentially equally spaced outstanding setting of each perisporium, forms trapezoidal shape.Therefore can generate uniform foam, trapezoidal shape can utilize NC processing to cut to make.

(13) emblem Aphron all living creatures apparatus for converting also possesses the second impeller on the axis identical with the first impeller, and this second impeller has a plurality of drawer at movable side perisporiums cylindraceous.In the situation that two impellers are arranged in generating apparatus, can consider along two impellers of axially-aligned, or radially be configured to nested type.In the situation that along axially-aligned and the axle of two impellers departs from, the deflection angle of impeller increases, consequently, this impeller and housing contacts, affect the rotation of impeller, possibly cannot obtain desirable performance.In the situation that radially configuring and making vane rotary, the difference of the circular velocity of internal diameter and external diameter increases, and at internal diameter, produces that circular velocity slows down and the unfavorable condition that can do nothing to help foam generated.In this point, if two impellers are configured in coaxially above, solved related problem points.

The first drawer at movable side perisporium 82d, the 82e of (14) first impellers 82 is identical with the diameter of the second drawer at movable side perisporium 84b, the 84c of the second impeller 84.Therefore can be that micro-bubble all living creatures apparatus for converting is compact, and easily manufacture.

(15) between the first drawer at movable side perisporium 82d, the 82e of the first impeller and above-mentioned the second drawer at movable side perisporium 84b, the 84c of the second impeller 84, form medial flange 75c, above-mentioned fixation side perisporium 75e, 75f, 75g, 75h extend along the both sides of above-mentioned medial flange.According to this structure, because fixation side perisporium is along the extending axially an of flange, therefore can make micro-bubble all living creatures apparatus for converting compact.

(16) mutually adjacent the first drawer at movable side perisporium 82d and the distance radially between the first fixation side perisporium 75e form constantly along the length direction of above-mentioned perisporium 82d, 75e, and the distance radially between the first drawer at movable side perisporium 82e and the first fixation side perisporium 75f also forms constant along the length direction of above-mentioned perisporium 82d, 75e.Flow path area is constant thus, can make the flow resistance of fluid even, thereby has suppressed pipe loss resistance.
